[Second Embodiment]
As shown in FIGS. 9 to 11, in order to provide the installation object support member 9 with a long hole direction changing mechanism for forming the bolt insertion portion 17 into a long hole and changing the longitudinal direction of the long hole. The base-side support member 5, the lid member 13, and the installation object support member 9 may all be formed in a cylindrical shape along the vertical axis so as to be rotatable around the vertical axis. That is, the 1st surrounding wall part 18, the 2nd surrounding wall part 19, the 3rd surrounding wall part 27, and the 4th surrounding wall part 32 are formed in cylindrical shape, as shown in Drawing 11 (a), (b), and (c), By changing the longitudinal direction of the bolt insertion part 17 by rotating the object connection member 9A relative to the support connection member 9B by 360 degrees, the attachment position of the connection bolt 16 is displaced in the two-dimensional direction in the lateral direction. It is configured to be freely adjustable. Note that the laterally long holes 31 of the lateral displacement mechanism are arranged in two stages in the vertical direction so that they can be selectively used when the connection bolt 23 is inserted through the relative rotation.
[Another embodiment]
Other embodiments will be described below.
<1> The installation object 3 may be a support frame of a solar cell panel or other device in addition to the support of the antenna as in the embodiment.
<2> The installation object support member 9 may be formed integrally with the installation object connection member 9A, in addition to the case where the installation object connection member 9A is divided into the support connection member 9B.
<3> The bolt insertion part 17 provided on the top surface of the installation object support member 9 may have a slit shape in addition to the long hole shape, and adjustment of the attachment position of the connecting bolt 16 is unnecessary. If so, it may be a round hole shape with a size that the bolt head simply locks.
<4> The first connecting portion 20 and the second connecting portion 21 are fastened together with the connecting bolt 16 and the nut N, and the lid member 13 and the installation object supporting member 9 are simultaneously connected to the base side supporting member 5. Although it was comprised so that it might be fixed, the 2nd connection part 21 is located in the position different from the 1st connection part 20 with respect to the 2nd surrounding wall part 19, and it connects separately with the separate connection bolt 16 and the nut N. You may form so that it may do. In this case, the second connection portion 21 provided on the installation object support member 9 is formed into a round hole, and the second connection portion 21 provided on the second peripheral wall portion 19 is formed as a vertically long hole to constitute a vertical change mechanism. It is also possible to do so.
<5> The base-side support member 5 constitutes the first connecting portion 20, and, as shown in FIG. 7, a metal belt-shaped reinforcing band plate 35 is provided on the upper edge of the first peripheral wall portion 18. The first connecting portion 20 may be configured by welding integrally over the entire circumference and attaching the nut N to the reinforcing band plate 35 by welding. Further, as shown in FIGS. 8A and 8B, a nut storage box member 36 that holds the nut N in place by being inserted from above may be welded. In this case, the nut storage box member 36 is made of a metal plate and is formed by bending a metal plate, and the bottom plate portion 36A is inclined so as to become lower away from the first peripheral wall portion 18, and a gap 37 is formed in the lower corner portion. (FIG. 8 (a)), even if rainwater enters from the upper nut opening / closing opening, it is configured to be discharged from the gap 37 to the outside. Further, when the nut N is inserted into the nut storage box member 36, the nut N received by the inclined bottom plate portion 36A is guided so as to be close to the bolt insertion hole 20A (FIG. 8A). However, in this state, the central axis of the bolt insertion hole 20A and the central axis of the nut N do not match, and the nut N is pushed from the bolt insertion hole 20A by the connecting bolt 23 so as to be close to the first peripheral wall 18. As a result, the axis of both insertions is set to coincide with each other (FIG. 8C).
<6> As shown in FIG. 12, the locking member 34 has a rod-like member that is in contact with the bolt head on the inside thereof and is integrally attached by welding to prevent the head of the connecting bolt 16 from rotating. Also good.
In addition, as mentioned above, although the code | symbol was written in order to make contrast with drawing convenient, this invention is not limited to the structure of an accompanying drawing by this entry. In addition, it goes without saying that the present invention can be carried out in various modes without departing from the gist of the present invention.
